SPECIFICATION forming part of Letters Application filed May 20, 1881.

To all whom it may concern Be it known that I, LUTHER C." CROWELL, acitizen of the United States, residing in the city of Brooklyn, countyof Kings, and State of New York, have invented certain new and usefulImprovements in Sheet Feeding and Registering Apparatus, fully describedand represented in the following specification and the accompanyingdrawings, forming a part of the same.

In the operation of printing sheets of paper, and especially in printingthe blank side of a previously-printed sheet, which latter sheets arenecessarily fed a second time to the printing mechanisms, as well as infeeding printed sheets as supplements to mechanisms co-operating withprinting mechanisms to deliver the sheets, so that a sheet just printedmay have a previously-printed supplement properly com bined with it, thegreatest feeding accuracy is required. This is accomplished in hand-fedtimes by register-points, and in some instances by pneumatic apparatus.In web-printing machines, however, where the long lengths of materialare printed at very high speed, the sheets are produced bytransverse-severing of the web after the same has been printed, and

the web is secured before the web is divided to form the sheets. In thepresent state of the art of rapid printing, more particularly that knownas newspaper-printing, now generally performed by rotaryprinting-machines, in which a long length of paper wound up in the formof a roll is fed through the mechanisms, printed up on both surfaces,and cut transverse 1y through the margins to form the sheets, saidsheets are either gathered into pairs, triplets, &c., to constituteawhole product, or the component sheets of the latter are simultaneouslycollected condition, or each successivesheet is folded and delivered. Ithas also become desirable and such printing-machines are now required tobe provided with a means for associating with each sheet or set ofcollected or folded sheets one or more whole or part sheets, calledsupplements, which supplement sheet or sheets must, as is obvious, he sodirected and governed in their travel through the mech- Patent No.278,777, dated June 5, 1883.

sheet or sheets, or into the mechanisms controlling the latter, that thesupplement-s'heet shall register with the main sheet, so that thecombined sheets forming the product shall have their margins properlyregistered. In book or pamphlet work this 'is particularlyrequisite,since the succeeding pages brought into juxtaposition by folding thesheets into book form must register to produce perfect work. Thecontrolling of the position of sheets following each other in rapidsuccession, either to printing mechanisms, to associating mechanisms, tofolding mechanisms, or to delivering mechanisms, is a serious problem,and requires a most sensitive governing mechanism that willautomatically and quickly regulate itself, for the reason that where thepaper travels at a high rate of speed the slightest in accuracy of feedwill quickly multiply, and

therefore soon destroy register, and result in much or too little aheador b6hlIl(1.-O2LUS6S said 80.

controlling mechanism to come into action, and so operate the feedingmechanism as to cause the succeeding sheets to assume the correctposition of register. Thus the sheets ar riving from any cause at thepoint occupied by this registering mechanism automatically act inpassing the same to set into operation the means for correcting thefaulty feeding movement, thereby not only preventing the extent to whicha sheet may be out of register from multiplying, but acting to cure thecause by restoring the correct position of the mechanisms, or impartingto them an adjustment that will produce proper register.

The embodiment of this invention illustrated by the annexed drawings isa structure par ticularly designed for attachment to web-printingmachines, and as thus embodied will be described, though its adaptationfor use with hand and other sheet feeding means is con-- 10o templated.

In said drawings, Figure 1 illustrates by a side elevation, Fig. 2 by aplan view, Fig. 3 by an end elevation, and Fig. 4 by a longitudinalsectional elevation, a machine provided with my improved registeringapparatus. Fig.

5 is an enlarged longitudinal sectional elevation of the sheet-feedingor position-controlling mechanism, of which Fig. 6 is a detail, and Fig.7 a plan view, showing more particularly the gearing. Fig. 8 representsa front elevation, and Fig. 9 a longitudinal sectional elevation, (bothdrawn upon an enlarged scale,) of the mechanism for printing,perforating or punching, and winding up a supplement-web. Fig. 10 is anenlarged plan view of the registergoverning mechanism. Figs. 11, 12, and13 are enlarged sectional elevations of said register-governingmechanism, showing the same in three different positions of itsoperations. Figs. 14, 15, and 16 are still more enlarged sectionalelevations of said register-governing mechanism, showing three differentadjustments of the sheet therewith. Fig. 17 is an enlarged plan view,and Figs. 18, 19, and 20 side elevations, of an electrical apparatusforming part of said registergoverning mechanism. Figs 21, 22, 23, 24,and are details of said electrical apparatus. Figs. 26, 27, and 28illustrate a modi -fied construction of said register-governingmechanism; and Figs. 29, 30, and 31 show such modified apparatus, bymuch enlarged views of the same, in three positions of operation.

That the purpose and conjoint operation of this register governingmechanism with the delivery mechanism of aprintingmachine may be morereadily appreciated, the structure and operation of the devices of saidprinting-machine and its delivery mechanism will first be explained, andthen the co-operation therewith of the register governing mechanism willbe explained. Referring, then, more particularly to Figs. 1 to 4, whichare general views, the machine thus represented is one provided withmeans for operating upon two sets of sheets fed independently to it, andit comprises a means for printing one or both of said webs, as the casemay be. It thus embodies here a rotating printing mechanism illustratedby the last type and impression cylinders A B, as well as cylinders G D,provided with cutting mechanisms coacting to divide, perforate, or punchsaid web. The cylinders A B are provided with toothed wheels 101 102,from which motion may be communicated to the various other rotatingdevices in proper time and direction through suitable gear-wheels. Thusthe cut ting cylinders, which are provided with toothed wheels 104 105,are driven by an intermediate, 106, while the delivery mechanism,

which is shown to be a gathering apparatus consisting of a cylinder orcarrier, E, and the necessary appurtenances, is set into timely mo-'tion by a train of wheels, 107 108 109 110 111 51 being stretched fromthe pulleys 53, thence over pulleys 54, and returned around pulleys 5.The tapes 52 are stretched from pulleys 55 and return around pulleys 56.These tapes 51 52 constitute a conveyer carrying the sheets from thecutting-cylinders O D toward the car rier E, and run in contact as faras pulleys 56, the space from which toward the pulleys 54 is spanned byconductors 57 while the space between the pulleys 5 and the cylinder Eis provided with a conveyer formed in part by the conductors 58 andtapes 59, which tapes 59 run from the pulleys 54, pass in contact withthe lower surface of the cylinder E, and return over pulleys 60 61. Athird set of tapes, 62, run from pulleys 63 in contact with the cylinderE and return over pulleys 64 and 65. Be tween the pulleys 60 and 63 aset of switches, 6, are provided, and these switches, together with thetapes 59 62 and conductors 58, form the means for guiding sheets uponsaid cylinder E and directing them around upon the surface thereof, suchswitches 6 also acting, when properly rocked, to enter their ends withinthe peripheral line of the cylinder E as a meansv for stripping a sheetor collected sheets from the surface of said cylinder, directing thesame outward therefrom between the tapes 59 and other tapes, 66 67, thetapes 66 extending outward from the pulleys 68 and the tapes 67 from thepulleys 61, and together constituting a conveyer for delivering thesheets to a piling or other mechanism. These several tapes will bedriven with uniform surface speed by motion derived from a toothedwheel, 151, with which the carrier E is provided, through toothed wheels152, 153, 154, 155, and 156, with which the pulleys 64, 5, 54, 82, and56 are provided, and wheels 157, 158, and 159, with which the pulleys63, 68, and 60 are provided. (See Figs. 11 to 13.) No furtherdescription of this gathering mechanism need be made, since it is or maybe substantially like that described in the Patents Nos. 192, 510,192,954, 193,056, 213, 793, and is now a well -known mechanism forrapidly delivering sheets; and it will be understood, therefore, that aweb ofpaper, as 99, may be led from a roll, as 100, through the printingmechanisms and the cutting-cylinders O D, and be severed or partiallysevered transversely by the latter to divide it into sheets or to defineits line of such division, which sheets will be conveyed by the tapes 5152 to the gathering cylinder E, and there be collected or associated toany desired number, and by the proper operation of the switches 6 thebody of collected or associated sheets be directed in a pack to thetapes 66 67.'

The carrier E mayof course be provided with suitable mechanisms, andform part of a rotating folding mechanismsuch, for instance, as thatshown in Patents Nos. 143, 674, October 14, 1873, and 171,196, December14, 187 5or be capacitated to gather as well as fold, as in Patent No.171,494, May 29, 187 7, or have the characteristics of constructionshown in No. 192,034, June 12, 1877.
